The Hidden Cost of Dirty Coolant In high-precision metalworking, coolant condition directly affects productivity and part quality. As tramp oils, fine metal particulates, and bacteria accumulate, coolant loses lubricity and thermal control, causing premature tool wear, poor surface finishes, and part rework. This is where Coolant Recycling Systems become essential. Many plants still manage coolant individually at each machine’s sump, […]

How Pharma Producers Turn Wastewater into a Strategic Asset Pharmaceutical manufacturers are under growing pressure to reduce water use, cut waste volumes, and comply with increasingly stringent discharge standards. Leading companies are turning wastewater from a liability into a source of measurable cost savings, sustainability gains, and brand differentiation. This is where PRAB’s pharmaceutical wastewater treatment technology becomes an important […]

Why Coolant Waste Costs More Than You Think Every CNC operation depends on cutting fluids to cool, lubricate, and flush chips away from tooling surfaces. Over time, these fluids become contaminated with tramp oils, metal fines, and bacteria—turning an essential asset into a costly waste stream. This is where PRAB’s Cutting Fluid Recovery systems optimize Coolant Recycling. Disposing of spent […]

Why pH Control Systems Matter in Industrial Wastewater Every manufacturing process that uses water, whether for cooling, cleaning, plating, or machining, creates wastewater with fluctuating pH. Those fluctuations can result from spent coolant, tramp oils, cleaners, or metal-bearing fluids. When pH drifts outside the EPA- or POTW-required 6.0–9.0 range, facilities risk heavy surcharges, permit violations, or even forced shutdowns. That’s […]

Metal Scrap Conveyor Selection Guide: Match Your Scrap, Coolant, and Throughput for Long-Term Performance Selecting the right metal scrap conveyor isn’t just about moving chips from A to B —it’s about reliability, throughput, coolant carry-over, maintenance load, and long-term total cost of ownership. With modern machining, stamping, and foundry operations running at higher speeds and volumes than ever, the wrong […]

Reduce Conveyor Downtime by Following PRAB’s Recommendations In metalworking and machining operations, chip nests (Bushy bundles)—long, stringy turnings that knot together—are among the most common causes of conveyor downtime. These tangled masses can bridge in chutes, wrap around shafts, and ride the return run, leading to stoppages, safety hazards, and costly maintenance. This guide explains how to prevent chip nests […]

Manufacturers are under increasing pressure to prove sustainability ROI. PRAB’s engineered systems—heavy-duty conveyors, coolant recycling, metal chip processing, and industrial wastewater treatment—convert sustainability goals into measurable business value: reduced costs, recovered materials, and verified compliance. Understanding Circular Economy Metrics When manufacturers speak of “circularity,” they often mean closing the loop: reducing raw‐material input, reusing what was once waste, and returning […]

Preventive maintenance (PM) enhances equipment reliability, reduces the total cost of ownership (TCO), and extends the service life of high-value manufacturing assets. PRAB® equipment—often still running after 30+ years—proves how disciplined maintenance translates into unmatched durability and ROI. Why Preventive Maintenance Matters Unplanned downtime is the largest hidden expense in metalworking and industrial operations. When a conveyor chain breaks or […]

Introduction: Coolant — the Hidden Cost Driver in Metalworking Coolant and cutting fluids are essential for precision machining, but they come with recurring costs. As these fluids degrade, manufacturers face increased tool wear, quality issues, disposal fees, and the expense of frequent fluid top-offs. Implementing coolant recycling can significantly mitigate these costs. Fortunately, modern integrated separation and filtration systems can […]

PRAB’s end-to-end systems—combining chip reduction, fluid separation, and coolant recycling—let manufacturers reclaim up to 75% of their cutting fluids and reduce waste disposal by up to 90%. Closed-loop chip and coolant recovery is no longer a “nice-to-have”—it’s now a profit-center and risk-reduction strategy. PRAB® has spent more than 70 years engineering and supporting USA-built systems that help manufacturers optimize their […]
